PCM tracks up to 24-bits/192-kHz, 2.8MHz and 5.6MHz DSD tracks are supported.
You can also enjoy listening to your music from your favorite portable device via wireless Bluetooth connectivity, and the PMA-50 features NFC touch pairing along with multi-point Bluetooth connectivity. For optimum wireless audio fidelity the PMA-50 features CSR aptX Low Latency decoding that delivers CD-quality sound.
There are multiple digital inputs (2 optical and 1 coaxial) for compatibility with digital audio sources along with an analog stereo input for legacy analog sources.
The advanced Class D digital amplifier features DDFA technology that provides high efficiency and low distortion and the PMA-50 is rated at 50 watts per channel into 4 ohms, for compatibility with the widest range of speaker types.
The compact chassis features deluxe styling and is sized to fit just about anywhere, including home and office desktops as well as home studios, and it can be positioned horizontally as well as vertically.
Advanced AL32 Digital
For the ultimate fidelity with 16-bit, 20-bit and 24-bit digital audio tracks, the PMA-50 features Denon's Advanced AL32 digital audio processing system. Featured on Denon's premium audiophile disc players and digital audio components, Advanced AL32 processing upconverts, digitally filters and noise-shapes lower bit data to full 32-bits, delivering remarkable dynamic range and noticeably better low level resolution. Your favorite digital audio tracks have never sounded better.
Full digital power amplifier
for powerful and detailed sound
The amplifier section incorporates DDFA® technology from CSR. The output stage circuit has a discrete construction which realizes higher Signal-to-Noise-ratio and lower distortion compared to conventional class D amplifiers. This advanced amplifier system delivers superior audio fidelity along with high amplifier efficiency at 50W into 4 ohms.
The premium grade multi-way speaker connectors let you connect speaker cables via bare wire, pin connectors as well as banana plug connectors.
DAC Master Clock design
In order to reduce jitter, Master Clock is re-generated in the PWM modulator. This Denon Master Clock design ensures that sound is correctly localized and your sound space is thoroughly realistic.
USB-B Input for High resolution
Audio including PCM and DSD
Via the USB-B input, you can connect your Mac or PC to the PMA-50 and enjoy high resolution audio tracks. The PMA-50 can play high resolution PCM files of up to 24-bits/192-kHz along with high resolution DSD 2.8 MHz and 5.6 MHz files (DSD is the advanced digital audio coding system of SACD). A USB-A to USB-B cable is included.
To eliminate induced digital noise via the USB input, the PMA-50 features a dedicated noise isolation block prior to the digital amplifier and D/A conversion block that prevents digital noise from degrading the audio fidelity.
Bluetooth Wireless Connectivity
with NFC and Multi-Point
Stream your favorite audio tracks from your portable devices via the PMA-50's Bluetooth connectivity, which features quick and easy pairing via the Bluetooth button on the front panel. Simply activate the Bluetooth function on your device, press the Bluetooth button on the front panel or the remote control and when prompted, enter the supplied 4 digit passcode on your device. Your device and the PMA-50 are instantly paired and up to 8 devices can be remembered.
For even faster pairing, the PMA-50 features NFC (Near Field Communication). Simply activate your NFC-enabled Bluetooth device and place it next to the N mark on the PMA-50 (located on the side panel), and it's instantly paired with no need for manual passcode entry.
Plus, the PMA-50 features Multi Point Bluetooth connectivity which allows 3 Bluetooth-enabled devices to be connected simultaneously. Play tracks from 1 device and when it's paused or stopped and another paired device's play function is activated the PMA-50 automatically switches to that device. The front panel display shows the name of the currently selected Bluetooth device.
aptX Low Latency Decoding
For CD-quality audio playback, the PMA-50 features the latest generation CSR aptX Low Latency decoding, which provides optimum time synchronization when playing back audio from video sources with no lip sync issues.

Advanced AL32 Processing
Advanced AL32 Processing, the new generation of the Alpha processor. It is capable of digital signals to expand not only in the resolution to 32 bits, but also leads an upsampling of the digital signals by up to 192 kHz.
The Alpha processor suppresses quantization and disturbing are the finest musical nuances, even in extremely quiet passages of music, again, of course. Thus, for example as well as conventional 16-bit CDs in 32-bit quality of service and with an extended frequency range kHz up to 80. The downstream high-quality 32-bit, 192 kHz-D/A-Wandler the latest generation ensure the faithful conversion of the signals in the analog world.
Advanced AL32 Processing The variation in multi-channel multi-channel devices to work simultaneously for all channels and smoother in operation for multi-fidelity sound reproduction.
